Synopsis:          Moderate: rust-toolset:rhel8 security, bug fix, and enhancement update
Advisory ID:       RHSA-2021:3063-01
Product:           Red Hat Enterprise Linux
Advisory URL:      https://access.redhat.com/errata/RHSA-2021:3063
Issue date:        2021-08-10
CVE Names:         CVE-2020-36323 CVE-2021-28875 CVE-2021-28876

                   CVE-2021-31162 
====================================================================
1. Summary:

An update for the rust-toolset:rhel8 module is now available for Red Hat
Enterprise Linux 8.

Red Hat Product Security has rated this update as having a security impact
of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AppStream (v. 8) - aarch64, noarch, ppc64le, s390x, x86_64

3. Description:

Rust Toolset provides the Rust programming language compiler rustc, the
cargo build tool and dependency manager, and required libraries.

The following packages have been upgraded to a later upstream version: rust
(1.52.1). (BZ#1953002)

Security Fix(es):

* rust: optimization for joining strings can cause uninitialized bytes to
be exposed (CVE-2020-36323)

* rust: heap-based buffer overflow in read_to_end() because it does not
validate the return value from Read in an unsafe context (CVE-2021-28875)

* rust: panic safety issue in Zip implementation (CVE-2021-28876)

* rust: memory safety violation in Zip implementation for nested iter::Zips
(CVE-2021-28877)

* rust: memory safety violation in Zip implementation when next_back() and
next() are used together (CVE-2021-28878)

* rust: integer overflow in the Zip implementation can lead to a buffer
overflow (CVE-2021-28879)

* rust: double free in Vec::from_iter function if freeing the element
panics (CVE-2021-31162)

For more details about the security issue(s), including the impact, a CVSS
score, acknowledgments, and other related information, refer to the CVE
page(s) listed in the References section.
